The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention more clearly is described, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of bench saw transmission mechanism of the present invention, comprise sawtooth 12, motor 11 and motor decelerating mechanism.Motor decelerating mechanism is preferably the belt speed reducer structure, and as shown in the figure, thereby belt 5 is walked around the rotor transferring power of belt pulley 4 and motor.Also be connected with a belt tension locking device between belt speed reducer structure and motor 11, the belt tension locking device comprises two connecting plates 13, and locking device 6, as shown in Figure 4, two connecting plates 13 are connected with the power transmission shaft of motor 11 and the central shaft of belt pulley 4 respectively, and described connected mode can be known connected mode, such as being threaded, riveted joint etc., the overlapping position of two connecting plates 13 is respectively equipped with connecting hole, and locking device 6 is through the connecting hole between two connecting plates 13.The belt tension locking device is for regulating the position of belt pulley 4: by changing two distances between connecting plate, can corresponding adjusting belt pulley 4 and motor 11 between distance, during adjustable range, motor 11 moves along motor slide rails 14 along continuous straight runs, belt pulley 4 adopts same central shaft with sawtooth 12, come transferring power to sawtooth 12, thereby make sawtooth 12 work, with cutting workpiece, the position of belt pulley 4 moves up and down along rail plate 10 in company with sawtooth 12, when belt pulley 4 and motor 11 are adjusted to correct position, by belt locking device 6, be fixed up in position between the two, belt locking device 6 can be any device that two connecting plates 13 can be fixed together, what the present embodiment was selected is to be threaded.Sawtooth 12 is fixedly connected with (such as welding, riveted joint, screw thread fixing etc.) with slide plate 8, the position by adjusting slider 8 on rail plate 10 can be regulated the position of sawtooth 12 the corresponding position of regulating belt pulley 4 easily.The position adjusting mechanism of slide plate 8 is: at the bottom of breast bench correct position, fix a thread transmission, use screw rod 1 and with protruding nut 2, by rotary screw 1, can drive nut 2 moves back and forth on screw rod 1, fulcrum 9 secured adjusted plates 3 are passed through on screw rod 1 top at breast bench, and make adjustable plate 3 can take fulcrum 9 to swing as axle, adjustable plate 3 is porose in the position corresponding with nut 2, be preferably the slotted hole of along continuous straight runs, make projection and the hole on adjustable plate 3 on nut 2 suitable, the opposite side of adjustable plate 3 is fixed with projection, be preferably projecting pin 7, porose with projecting pin 7 relevant positions on slide plate 8, projecting pin 7 on adjustable plate 3 is suitable with the hole on slide plate 8, preferably, the slotted hole that hole on slide plate 8 is along continuous straight runs.The position of projecting pin 7, slide plate 8 and rail plate 10 as shown in Figure 2.
As shown in Figure 3, during work, make screw rod 1 rotation by External Force Acting, screw rod 1 rotation can drive the nut 2 matched with it and move back and forth on screw rod 1, projection on nut 2 is punctured in the corresponding slotted hole of adjustable plate 3, and make adjustable plate 3 take fulcrum 9 to swing as axle, projecting pin 7 on adjustable plate 3 is punctured in slide plate 8 in corresponding slotted hole, thereby can drive slide plate 8 moves up and down on sliding rail 10, because sawtooth 12 is fixed on slide plate 8, thereby make the upper-lower position of sawtooth 12 on breast bench change.Because sawtooth 12 and belt speed reducer structure link together, by regulating the position of two gripper shoes between belt speed reducer structure and motor 11, the position of fast pulley 4, reduce gearing friction easily.
The advantage of the present embodiment is, the low cost of manufacture of drive disk assembly is processed easyly, can realize continuous transmission, and noise is little, vibrates littlely, enhances productivity.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
